John Hagan, PhD, Professor of Sociology and Law at Northwestern University, and Alberto Palloni, PhD, Professor of Sociology at the University of Wisconsin, in a Nov. 1999 Social Problems essay entitled "Sociological Criminology and the Mythology of Hispanic Immigration and Crime," concluded that:

“Our sociological knowledge of crime is fragmented and ineffective in challenging and correcting mistaken public perceptions, for example, linking immigration and crime. These misperceptions are perpetuated by government reports of growing numbers of Hispanic immigrants in U.S. prisons…

[I]t is estimated that the involvement of Hispanic immigrants in crime is less than that of citizens. These results cast doubt on the hypothesis that immigration causes crime and make more transparent the immigration and criminal justice policies that inflate the rate of Hispanic incarceration.”
